Troubleshooting instructions
1 Check if the shelf containing the affected card has raised a Fan alarm: FNLOW, FNLOWM, FNUPP, or FNUPPM, and troubleshoot any such alarm first.
2 If the TempP# alarm persists, check the ambient temperature around the shelf. It must be lower than 50°C (122°F) or as otherwise quoted in the official SURPASS hiT 7500 product specifications.
3 Contact your next level of technical support before proceeding since the following action is traffic-affecting. If no other cause can be found, Warm Start the card raising the alarm. If the TempP# alarm persists after Warm Start recovery time (approx 3 minutes), Cold Start the card. If the TempP# alarm persists after Cold Start recovery time (approx 3 minutes), the card is defective. Replace the affected card with a spare.

3.1.143 TimP
Troubleshooting instructions
1 Is traffic affected due to the TimP condition?
– Yes: Warm Start the card raising the TimP alarm. Sometimes, this allows a failed card to recover. Note however, that the recovery is often only temporary.
If the Warm Start does not clear the alarm, Cold Start the card. If the Cold Start does not clear the alarm, immediately replace the failed card with a spare.
– No: Warm Start the card raising the TimP alarm. Sometimes, this allows a failed card to recover. Note however, that the recovery is often only temporary. If the Warm Start does not clear the alarm, do NOT execute a Cold Start. Wait for the next scheduled maintenance window to replace the faulty card.
2 If the alarm persists, contact your next higher level of technical support.
